The main memory configuration of both the TIGERSearch and TIGERRegistry tool and the corpus base directory used by the two tools can be modified in the Software suite preferences window. It is opened by selecting the Software preferences item in the Options menu of the TIGERRegistry tool:
Figure: Software suite preferences
The following software suite parameters can be specified:
Memory configuration
Whereas the TIGERRegistry tool will always work fine if you have the required 256 MB main memory on your system, the TIGERSearch tool could lack on main memory if you work with very large corpora. Unfortunately, a typical feature of Java applications is that the initial main memory size (used when starting an application) and the maximum main memory size (that can be used by an application) have to be specified before the application is launched. So if you have more than 256 MB main memory installed on your system, this additional memory will not be used automatically.
If you want to increase the maximum main memory used by the TIGERSearch tool, just type in the new memory size in the max text field. We recommend you also to increase the initial memory used when an application is started - preferably a quarter of the maximum main memory. This will increase the corpus loading speed.
The TIGERRegistry tool should work without any problems using 256 MB memory. Nevertheless you can also change its memory configuration.
Corpus base directory
The corpus base directory used by the TIGERSearch software suite is created during the software installation as a subdirectory TIGERCorpora of the installation directory.
You can move the directory to another location (e.g. to another hard disc drive) as follows:
First create the new (empty) corpus directory.
Then open the software preferences window in the TIGERRegistry tool and specify the new directory in the Corpus directory text field by typing in the absolute path or using the file chooser. After submitting, the TIGERRegistry tool will be closed automatically.
Move the content of the old corpus directory to the new corpus directory.
Submit modifications
If you modified the memory or corpus directory configuration, press the Submit button. The modifications will be checked and the software suite configuration will be changed. As the status of the sofware suite has changed, the TIGERRegistry tool will be closed automatically. To profit from the new software configuration you will have to restart your current TIGERSearch session.
Please note:
The modification of the software configuration files
is realized in a platform-independent way. Thus, the file permissions
of the modified configuration files may change, depending on your
default settings. So if you have installed the
TIGERSearch software on a multi-user system, please check the file
permissions of the modified configuration files. These are the two
files TIGERSearch.lax and
TIGERRegistry.lax in the
bin/ subdirectory of your
TIGERSearch installation directory.
